so after finally resolving all my head and tail issues I've been flying the 3D Plus yesterday and enjoying it very much. I have an OS 55 and OS Powerboost pipe combo in it and it is supposed to produce decent power I've heard. So for the first few flights it was ok but nothing spectacular. Weather was kind of hot and humid. Well at some point the temperature dropped and it became a little windy. As soon as that happened the heli started flying like it's on crack! I could not believe how fast and powerful it became because out of 3 gallons I ran through it so far it was the first time I felt that power. Well that means I haven't yet learned to tune the engine properly. But at least now I know what it is capable of and I am liking it. I mean all I can say is WOW! 3D Plus ROCKS!
